The Gradav Guide to

Sennheiser 3000 series

Radio Mics

Intro & Overview

The 3000 series of Radio Mic equipment is used in West End Theatre

productions, by Broadcasters, and those users looking for that extra quality

that is inherent in Sennheiser’s more expensive systems.

The EM 3032 dual receivers allow the user to the system. Output

level adjustment, squelch control and a comprehensive LCD display are

there for the experienced user. A headphone socket per channel is a handy

facility for all users.

Metal casings are used throughout the range giving an improved RF

performance, and a greater robustness.

Where transmitter size is important we have the SK5012, which is much

smaller than the SK50/SK3063 pocket packs. There is a small cost for the

reduction in size, and the SK5012 does not indicate battery life on the

receiver as do all the other transmitters.

This guide has been written to assist the user who is new to this system to

get the result they are looking for with the minimum of time and worry. It

will also aid the experienced user whose memory needs a little help!

Fault finding is never easy, especially when you are under pressure. We

have added a section that may just save your reputation (and sanity)!

Pocket Pack Transmitters

SK50 & SK3063

These packs are identical in operation

and are distinguished by the silver

body of the SK50 and the black body of

the SK3063.

We supply these transmitters with the

aerials fitted. The connector (1) is a

screw-lock single pin Lemo connector.

It is important that the locking ring is

tight.

Microphones to fit socket (7) are either

fitted with a screwdown connector (as

the aerial) or more frequently with a

push to insert type; where a pull on

the barrel both unlocks and removes

the connector. Never unscrew this

style of connector as internal damage

results, often leaving the connector

stuck in the transmitter. This is a 3

pin Lemo connector, to prevent acci-

dental insertion in the aerial socket

(and vice versa).

The channel selector switch (2) is

screwdriver operated. Frequency allo-

cations are as shown on the front

panel (8).

There is a multi-segment LED display on the battery pack that gives an indication of

battery life (3). See the chart above.

The ON/OFF switch (4) is recessed to avoid accidental operation. When the transmit-

ter is on the LED (5) will light. This LED will flash in the event of input (microphone)

overload. Reduce gain on the screwdriver operated input gain control (6). We find that

a setting of 3 suits most applications.

To remove the battery pack you must first squeeze the

catches either side of the trasmitter as shown. Slide the

pack downwards while continuing the pressure on the

catches. Install MN1500 (AA) batteries. Replace battery

box by sliding back into position.

We supply these transmitters with the aerials

fitted. The connector (3) is a screw-lock single pin

Lemo connector. It is important that the locking

ring is tight.

Microphones to fit socket (1) are either fitted with

a screwdown connector (as the aerial) or more

frequently with a push to insert type; where a pull

on the barrel both unlocks and removes the

connector. Never unscrew this style of connector as

internal damage results, often leaving the

connector stuck in the transmitter. This is a 3 pin

Lemo connector, to prevent accidental insertion in

the aerial socket (and vice versa).

The channel selector switch (5) is screwdriver

operated. Frequency allocations are as shown on

the panel (7).

To open the battery cover you must squeeze the catches on

either side and move towards the hinge, as shown by the

small arrows on the diagram, on the left.

When they have reached the end of their travel you can

hinge the cover open. This gives access to change the battery

set of 2 x MN2400 (AAA). Please check for polarity when

inserting.

Open this cover to give access to the controls etc as below.

Close the cover when you have finished. It will close with a

click as the catches engage. This arrangement prevents

accidental access to the controls, but the LED (2) is still

visible.

When the On/Off switch (6) is moved to the ON position, the LED (2) lights. The LED

will start to blink about 30 mins before operation will cease. The rate of blinking will

increase as the battery life diminshes.

Screwdriver switch (4) is used to adjust the input gain. We test at a setting of 3, and

find this level suits most applications. If the input is overloaded the LED (2) will flash

brightly.

This is a particularly small transmitter, with a case size of 53 x 60 x 17 mm.

Hand Held Transmitter

To change the MN1604 (PP3) battery, you

must first unscrew the capsule as shown.

Pressing against the side of the battery

compartment cover will release the lid, allow-

ing the old battery to be removed.

Replace the battery, ensuring that the rubber

transit cover has been removed from the

battery terminal, and that the correct polarity

has been observed. The transmitter terminals

have been designed to prevent operation

should the battery be inserted with the wrong

polarity.

Close the cover and replace the capsule to

ready the transmitter for operation.

Press the button briefly in the end of the

transmitter, as shown, to turn the transmitter

on. There is a delay of about 2 seconds before

the self-test checks are complete and transmis-

sion begins.

Press the button for > 1 second to turn off.

All the frequencies shown can be used together, although it is worth noting that as the

number of frequencies in use increases, so does the likelihood of external conditions

affecting system performance. Always take great care over receiver aerial placement

when using a large number of channels together.

remains, the receiver display shows

“LOW BATT” (D4).

If squelch is activated “MUTE” will

light, and the “LOW BATT” will extin-

guish. It will relight when a signal is

received from the transmitter.

Operation

Check that all the items on the delivery note have been supplied, before you

assemble your system. Please report any shortages immediately. We have less

sympathy with a claim that goods were not supplied after the hire has ended, than

we have for a shortage reported at the beginning.

In particular, note the number of tie clip microphones and their associated clips.

Both can remain attached to costumes, and just vanish at the end of the show!

Connect receivers to mixer inputs and attach all aerials.

Single kits have their aerials attached, and these need only to be extended and set as

shown in the cover picture.

Multi-channel kits are supplied with 2 Dipole aerials that are connected to the ADA

(Aerial Distribution Amplifier) and this supplies RF signals to all receivers. Dipole

aerials should be a minimum of 3 metres apart. Set with the elements vertical. Note

that on UHF aerials there is a moulded ‘E’. This is to show which element should be

at the bottom. VHF aerials have a whip for the upper element, and a helical for the

lower.

Failure to set aerials correctly can affect performance in a marked manner. It is

worth spending time experimenting with aerial location, for a small change can

often transform system performance.

Where we have supplied a flightcased system, you should note that we number the

transmitter, it’s receiver and output cable with corresponding channel numbers.

Power up by connecting to the mains and remember to switch on the ADA (Aerial

Distribution Amplifier). Failure to switch on the ADA will not prevent operation, but

the loss of RF signal will drastically affect performance.

Receivers lock onto the strong signals of their matching transmitters. In the abscence

of such a signal they will accept unwanted interference (known as intermodulation

interference - often shortened to ‘intermod’ ), which can light several segments of the

RF display. There is usually little or no audio present, but it can be confusing if

displays light on channels you weren’t expecting!

Failure to set aerials correctly can affect performance markedly. It is worth

spending time experimenting with aerial location, for a small change can often

transform system performance.

Always test multichannel systems with all transmitters switched on.

Always collect the transmitters at the end of the show. Change batteries if

required, and conduct your checks straight away. It is better to discover a

problem at the end of a show, rather than 10 minutes before you need it next

time!

Only when you are satisfied, should you distribute the transmitters. If you are not

planning to use them immediately it may be best to switch off the transmitters. When

all are switched off you should check the receiver displays. It will soon be obvious if

you have missed one!

Handheld transmitters present fewer operational problems than do Pocket Packs.

They are more likely to get dropped (or lost!). Stress to all users that they must take

care until the transmitters are returned to you.

Pocket Pack transmitters can be disguised quite easily with most costumes, but do

remember that aerials must be vertical. We offer black microphones as standard, but

pink models are available if requested at the time of ordering.

Headband microphones are available (MKE48) at an extra

cost.

NB2 adaptors are used with standard microphones (MKE2)

as shown in the illustration. There is a charge for these

adaptors.

Never stick aerials to skin

Capacitive coupling of aerial to skin (body) leads to high RF absorbtion, with a

reduced effective output to the receiver. Avoid placing packs/aerials next to the

skin. Sweat will always affect RF output.

CHECK - every performance

Each channel in turn for RF signal strength and audio quality.

Inspect for damage to every microphone cable and connector.

Transmitter aerial for cable damage and ensure that the connector is tight.

Sensitivity (gain) switches get moved. Re-set if required.

Extra microphones are available should you wish to between different users.

We supply some spares with hires. Spare aerials and microphones are sealed and

clearly marked. They should only be used in the case of failure.

Trouble Shooting

Distorts Input overload. Check the setting of the gain switch on

the transmitter.

Overload in the mixer input. Reduce output gain on

receiver and/or reduce input gain on mixer.

If headworn, check the position of the microphone

capsule.

No RF shown on receiver Check that the transmitter is on.

Is the battery OK? Try another one.

Has the rubber transit cover been removed from the

battery?

Has the battery been inserted correctly? Check polarity

Intermittant RF Check that the battery is properly installed.

Inspect the transmitter aerial for damage and loose

fitting.

Check that the transmitter aerial is straight and as

vertical as you can manage.

Body absorbtion of RF. Check that the transmitter

aerial is not stuck to the skin with tape. Avoid contact

of aerial with skin if possible.

Works, but hisses A faulty capsule. They can fail by giving low gain.

Substitute a good microphone from another pack, or

use the spare if only 1 pack is in use.

A level mismatch, where a low signal is amplified by

the next stage increasing background hiss to audible

levels. Below are the most likely solutions to this.

Reduce input gain on mixer, increase receiver output.

Set attenuation setting to high on tranmitter. If disto-

tion results, return to original setting.

Sweat in the pocket pack

transmitter

Some actors (and some locations!) produce a lot of

sweating. Ingress of sweat can affect performance.

Consider re-positioning the pack on the actor.

Take a child’s balloon and trim with scissors so that

you can encase the whole transmitter (not aerial!) in

a waterproof covering.

Works only when close

check that frequency of transmitter and receiver

match.

Aerial placement. Move each dipole aerial in turn

checking the signal strengths on the RF displays for

improvements.

Check transmitter aerial for looseness and damage.

Check receiver aerials are vertical and with the [E]

element at the bottom.

Experiment with receiver aerial positions, while ob-

serving the RF displays on the receivers.

Microphone crackles Screw-lock connectors need to have their locking ring

tight. Check for looseness.

Snap fit connectors should be fully home.

If you think you have found a faulty microphone, test

your suspicions by substituting a working micro-

phone from another unit. Then confirm by trying the

suspect microphone on a pack that is known to work

without crackling.

Scraping noises Check that the capsule does not come into contact

with costume or jewellery.

Cable scraping can cause spurious noises. Secure the

microphone cable by passing it inside the crocodile

jaws of the clip, creating a small semi-circular loop of

cable just below the microphone capsule. Scraping

noises travelling along the cable should be stopped

where the cable is gripped.
